1. Answer: 15.7143
log (7x-10)=2
Use the identity: loga(x)=b = x=(a)(b)
7x-10=10^2
Evaluate the Power
7x-10=100
Addition Property of Equality
7x=110
Division Property of Equality
x=110/7 or 15.7143
2. Answer: 0.3107
log(3)+log(x^-3)=2
log(3x^-3)=2
log(3 x 1/x^3)=2
log(3/x^3)=2
3/x^3=10^2
3/x^3=100
3=100x^3
3/100=x^3
Answer Cube root 30 / 10 or 0.3107
3. Answer: 0.002
log(5) + log(x) = -2
log(5x)= -2
5x= 10^-2
5x=1/10^2
5x=1/100
x=1/500

Honestly I could tell you the steps, but I do not have a lot of time. Sorry. I will comment later if you need the steps
Answer:
x=−3y−15
Step-by-step explanation:
Let's solve for x.
x+3y=−15
Step 1: Add -3y to both sides.
x+3y+−3y=−15+−3y
x=−3y−15
Answer:
x=−3y−15
Flip the x and y like in the coordinate plane x,y not y,x
Answer:
(u+5)(5+p)
Step-by-step explanation:
5(u+5)+p(u+5)
We can factor out (u+5) leaving behind 5+p
Putting that in parentheses
(u+5)(5+p)
This is the factored form
